To all whom it may concern.-

Be it known that we, JOHN A. L-ANNERT and WILLIAM R. J EAVONS, citizens of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Hydrocarbon-Burners; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to hydro-carbon burners, and the object of the invention is to provide an improved burner in which either the heavier or the lighter'hydro-carbons may be burned, and which will vaporize theoil within itself or burn vapor produced in the supply pipe or other outside means of generation, all substantially as shown and described and particularly pointed out in the claims.

In the accompanying drawings are shown three several views, which are modifications of one another, the idea in each case being to have a central vapor supply and a radiating supply from that point.

Thus in Figure 1 we have a central vertical section of the main or lower portion of a burner constructed accordiug'to this invention, the immediatebottom of theburner being conical or funnel shaped with a vapor holder in its bottom. Fig. 2 is a vertical central sec- .tion of another form of burner differing from the foregoing only in degree, so far as shape is concerned, but having the oil or vapor supply directly in the bottom of the conical base, instead of at the side as in Fig. 1. Fig. 3 is a vertical central section of a third form of burner, in which the bottom of the burner is substantially bowl shaped and with an oil or vapor holding portion in its center and bottom, as in the other forms shown, and with the supply thereto from above, all as hereinafter more fully described.

In the several views A and 13 represent the tubes between which the vapor is diffused and gradually consumed at successive eleva tions as fresh air is admitted into the chamber between said tubes through the perforations therein. In Fig. 2 these tubes extend from end to end of the burner, in continued funnel shape. But in Figs. 1 and 3 they are associated with bottom portions or extensions tremity which rests on the bottom of the bowl or holder d. This serves to support and center the inner portion D of the bottom and the tubes forming the diffusion chamber are perforated to admit air into the chamber, except the inner base tubes D and F of Figs. 1 and 3 respectively, and yet the tube or portion D might be perforated and work and the .portion F might also be perforated above its immediate bowl or trough-shaped portion f and likewise be operative.

In all the figures two or more air inlet openings orpassages h are shown to provide a free supplyof airto the inside of the burner. One or more of these passages may be provided.

In Fig. 1 the oil or vapor supply tube enters the space between the portions 0 and D from the outside and above the bowl or holder d. In Fig. 2 the funnel-shape of the burner tubes extends the full height of the burner, and the outer tube converges to a point in which is the space or holder for the oil or vapor; In this case, however, the supply pipe leads directly into the bottom of the holder orbowl cl. A cross brace It supports the point of the innor tube B, and centers said tube in the outer tube A. In all the views the short pipes h contribute also to this result.

In Fig. 3 the upper plate F of the bottom is not only primarily bowl-shaped, as is also the lower plate E, but the immediate bottom thereof is struck up slightly so as to rise above the surrounding surface and thus form a holder for the oil or vapor. Then in order that only a given quantity of oil or vapor may be thus held or detained, the struck up portion f has a comparatively large opening through its center through which the overflowing oil or vapor drops into the bowl orholder d in the bottom of the tube portion E, a subtube B connected thereto at its top. All the ICO stantially V-shaped support 12. corresponding to like support-s or stays. The oil or vapor is discharged from pipe G in Fig. 3 into the primary bowl or holderf, and from this point it overflows through opening f into the lower bowlor holder d, from which the vapor supplies combustion. In this view, thimble-shaped projections a and b are shown as formed on tubes A and B to center said tubes in respect to each other. The inner and outer Walls are described as converging to a common center, and by this is meantacommon vertical plane on which the converginglines meet as shown.

Obviously a single struck up projection extending entirely across the combustion chamber could be substituted for the two opposed projections a, b. The projections a and b are struck up from the stock or material of the tubes A and B, and are shown in Fig. 3 as at or near the top of said tubes, the means at the bottom of the two converging walls being relied upon to center the parts below. But projections like a and b, or either, may be used between said tubes or walls wherever found desirable.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. A hydrocarbon burner having walls forming a diifusing chamber, the lower portion of said walls constructed to gradually reduce the area of said chamber,a vapor supply, and air inlet openings to said chamber at successive distances from said vapor supply, substantially as described.

2. A hydrocarbon burner having a vapor supply at its bottom, a diffusing chamber formed with walls constructed at their lower portion so that the vapor as it travels expands into increasing areas within the diffusing chamber, said chamber provided with openings to admit air thereto at successive distances from the vapor supply, substantially as described. a

3. A hydrocarbon burner having walls forming a diffusing chamber and a vapor supply for said chamber, said Walls constructed to diltnsc the vapor in all directions from the vapor supply inlet, and air inlets for said chamber at successive distances from said vapor supply, substantially as described.

4. A vapor burner having a vapor supply at its lower portion, a diifusing chamber formed with walls extending outward and upward from said supply and having air inlet openings at successive distances to supply air thereto, substantially as described.

5. A vapor burner having a vapor supply in its bottom and adilfusing chamber formed with walls extending outward and upward from said supply, and an air passage or passages leading from the outside to the inside of the burner transversely through said chamber, substantially as described.

6. In hydro-carbon burners, a pair of concentric tubes forming a diffusing chamber between them and having struck up projections on their inside to support said tubes laterally, substantially as described.

\Vitness our hands to the foregoing specification.
